MAGAZINE CATCH AND RELEASE.

T (ill whom it may concern 7 Be it known that I, GRANT HAMMOND, a: citizen of the United States, residing at New Haven, in the county -of New Haven and V State of Connecticut, 'haveinven'ted a new 1 and Improved Magazine Catch and Release,

of which the 'following is a specification.

My invention relates to the class ofdevices "employed to receive ammunition and to be placedzin a'firearm 'for the use of the ammunitiorr therein, and :an object of my invention, among others, is to provide simple and 1 effective means-for holding such a device in place and for automatically effecting its=discharge when it is empty.

One form-of device embodying my invention' and in the construction and use of which the objects herein set out, as well as others, may be attained, is illustrated in'the accompanying drawings, in which- Figure 1 is a view in lengthwise section through a-"magazine embodying my invent ion, =a breech-bolt being shown in dotted dines.-

the same with parts broken away to show construction, the

line of -view being I angles'ito the aiiis of the magazine and the catchf being shown Fig. 3 is a view similar to Fig. 2, but with cartridges in the magazine, and further illustrating "that'por'tion of the handle with which the catch engages and the relative breech-bolt with respect to location of the when it is in place, the magathe magazine in the handle. '1 ,Fig. 4 is a detail side view of the lower part ofthe handle of a firearm embodying f my invention.

In the accompanying drawings the numeral 5yindicates a portion oftheffr'ame or 'handleof my improved firearm, 6 a portion E'of a gfip piece, and '7 the breech-bolt, all of i be of any suitable 'form and material. ffTMy improved magazine 8 may be of any suitable form to 'fit within the handle of the firearm in 'amanner commonto devices of this class, said magazine containing a follower' spring .9 pressing upwardly against a V cartridges 23 rest in away that-will be readily understood.

substantially at right:

in its releasing position.

Specification of Letters Patent. I Patented J 11119 24, 1919, Application filed Decemberil, 1917. Seria1No. 204,924.

-- .Theqbottom 11 of the magazine may be secured in place in any :eflicient manner and a locking bolt recess 12.;therein receives a locking bolt 13 and that is Seated against a locking bolt spring 1 1 in the bottom of the recess. The end of the bolt is ,-:arrangedto engage a keeper socket inf'the frame or handle and :a bolt actuating lever 15 is ipivotally mounted on the bottom with one end opera tively engaged with the locking bolt, the other end being connected as 'by a-chain or 'other extensible fleX-ible'connection 16 with the follower 10. In the special formof construction herein shown the lever 15 is a bellcrank lever, one end being engaged in a notch 17 in the locking bolt. In one form of bolt contemplated by me the end of the :bolt is forked providing two prongs, one of which 18 constitutes alocking prong that enters a keeper socket 19 in the frame, and the other prong 20 of which constitutes a thumb piece projecting outwardly into a recess 21 in the outer surface of the handle and by means of which the bolt may be manually actuated to release the magazine.

From the above description, taken in coninection with the accompanying drawings, it will beunderstood that when the magazine is fully loaded the follower 10 will occupy its lowermost position, :and as the cartridges are successively moved into the barrel by the operation of the breech-bolt 7 the follower will gradually rise. The chain or connection 16- :is of-such length that it will be drawn taut preferably by further movement of the follower after the last cartridge in the magazine has been forced into the barrel and after the follower has been brought to rest against the under side of the breech-bolt as shown in Fig. 1 of the drawings, the chain being of such length that at this time no force is exerted to disengage the locking bolt 13 from its keeper. It will now be understood-that when the firearm is operated to fire the lastcartridge which has been thus placed in the barrel, the breech-bolt will be forced backwardly and will be retained in this positiofn'in a manner common to automatically acting firearms, n connection with which myimproved magazine is'designed to be employed. When the breech-bolt has passed 'backwardly in this firing operation beyond the follower 16 the latter will spring upwardly and consequently the connection- 16 will be drawn taut and the lever.15 will be'actuated to withdraw the locking bolt 13. f'rom its keeper and the magazine'will fall by gravity or otherwise'ilfr'om its chamber 24 in the'handle, the thumb piece 20inithis operation passing out through a slot 22in the bottom portionof the handle? The end of the locking prong'18 is curved or beveled so that when the. magazine is inserted inthe,

It will be noted that as theffollowergl0 F gradually, in its 'fee'dingz-movement, ap-v 1 7.

and intent of the invention.
